Viktor is the AI coworker. It lives in Slack and Microsoft Teams, connects to thousands of tools, and does real work for real companies: finance, marketing, ops, engineering. We're building the product that replaces half the SaaS stack with a single teammate.
The team is small. The scope is not.
You own every pixel between a paid click and Viktor signup. At significant monthly paid spend climbing fast, every point of conversion lift is six figures of ARR. No team above you, no team below you yet. You ship.
The opportunity
Zeta runs serious paid spend across Meta and Google, scaling toward 2x volume in the next two quarters. Conversion is the lever that determines whether that spend pays off. Right now there's nobody owning it end-to-end — landing pages, funnel optimization, CRO, site IA. You'll be the first.
You inherit live momentum. The Media Buying LP shipped recently and is already the best CPA in the account. The E-commerce LP and Agencies LP are next up. MS Teams expansion is imminent. The runway is paved. The job is to keep shipping, faster.
Start: ASAP
Location preference: primary: EU (Warsaw · Paris · London · Berlin · Amsterdam · Helsinki · Stockholm · Istanbul), secondary: New York City
What you'll own
Paid LP velocity. Net-new landing pages weekly. Ship-in-three-days as the standard for fresh LPs. Every paid sub-segment we open up gets its own dedicated surface, and you're the person making sure that surface exists before the spend turns on.
CRO experimentation. 4-8 live tests at any given time, 2-3 shipping per week by Day 60. No button-color theatre — real tests on hypotheses that move the needle.
Signup funnel optimization. Everything from paid click to the moment the user hits signup. Handoff to the Growth PM at signup, but until then it's yours.
Site information architecture. A 90+ day deliverable. You ship it incrementally, not as a big-bang redesign.
Growth engineering. You ship code solo until Phase 3 brings on a dedicated Growth Engineer. Comfortable in the IDE is non-negotiable.
The bar
This role is 1.5 jobs if you don't prioritize ruthlessly. You'll be measured on shipping velocity, conversion lift, and CAC efficiency — not on roadmap polish. You set the playbook because there isn't one yet.
Day-1 reality
Week 1: unblock E-commerce, scope Agencies + MS Teams LP work, take over Media Buying CRO.
30 / 60 / 90
30d: Site + funnel audit. 3 CRO tests live. E-commerce LP unblocked + shipped.
60d: 6+ LPs. 10+ tests, 3+ winners. Paid→signup +10-15%. Rebrand migration plan ready.
90d: +15% conversion lift vs Day-30. LP production <3 days. CRO 2-3 tests/week. Vertical LP playbook documented.
Must-haves
3-7 years principal-IC web lead / growth engineer / founding CRO at PLG B2B SaaS or consumer fintech with $500K+/mo paid
Ships code + design solo. React + Tailwind. One of (Next.js, Astro, Remix). One no-code (Framer or Webflow) at production.
AI-native workflow: Claude Code/Cursor + V0/Lovable/Bolt + Framer AI/Webflow AI + Figma Make
CRO rigor — power calcs, hypothesis framing
Taste — LPs don't look like templates
Solo-shipping instinct — "I'd hire 3 people" = instant no-hire
How we work
Small team, high trust, low process. Decisions are made by owners, not committees. You will ship your first week. You will talk to users your first day. We don't do alignment meetings or stakeholder syncs. We build things, see if they work, and iterate.
Everyone here owns something real. Not a task. A surface of the company that customers depend on. When it breaks, you fix it. When it wins, everyone knows whose work it was.
We use Viktor to build Viktor. You'll see what you're working on in action every day.
Why Viktor
This is a rare window. The product works. The market is pulling. The team is small enough that what you do next week will be live in production next week. That doesn't last forever. Right now, it's still true.
Compensation
Competitive salary, meaningful equity, and the kind of ownership that only exists at this stage.
We're in Munich, New York, and Warsaw. Onsite preferred. The best work happens when you're in the room.
Viktor is the AI employee that lives in Slack and Microsoft Teams, connects to 3,200+ tools, and does the work.
